Moduli Spaces and Related Topics | On the moduli space of certain plane sextic curves

Venue:C654, Shuangqing Complex Building A 清华大学双清综合楼A座 C654

Speaker:YiMing Zhong (BICMR)

Abstract:

We study moduli spaces of certain sextic curves with a singularity of multiplicity 3 from both perspectives of Deligne–Mostow theory and periods of K3 surfaces. In both ways we can describe the moduli spaces via arithmetic quotients of complex hyperbolic balls. We show that the two ball-quotient constructions can be unified in a geometric way. This is a joint work with Zhiwei Zheng.

      Moduli Spaces and Related Topics | Curves on K3 surfaces and Mukai’s program

      Abstract:The Mukai’s program seeks to recover a K3 surface X from any curve C on it by exhibiting it as a Fourier-Mukai partner to a Brill--Noether locus of vector bundles on the curve. In this talk, I will give an introduction to work of Feyzbakhsh for Picard number one K3 and primitive curve C. We extend the results to the case of non-primitive curves by introducing the tools of destabilizin...
